The transformer coupled class A power amplifier was introduced to minimize low output power and efficiency issues of conventional class A amplifiers. It uses a transformer in the collector load circuit for impedance matching between the transistor and load. The transformer allows impedance matching by transforming the high impedance primary to a low impedance secondary connected to the load. This improves gain and efficiency over a standard class A amplifier by preventing signal power loss in resistors and providing DC isolation between stages.

Presentation on half and full wave ractifier.ppt
Kawsar Ahmed presented on half wave and full wave rectifiers. The half wave rectifier only conducts current during one half of the AC cycle, resulting in a lower output. The full wave rectifier uses two diodes or a bridge configuration to conduct current over both halves of the AC cycle, doubling the output. A center tap full wave rectifier uses two diodes and a center tapped transformer, while a bridge rectifier eliminates the need for a center tap and uses four diodes. Both full wave rectifiers provide an output with less ripple and higher efficiency than the half wave rectifier.
Application of diode
A diode is a two-terminal electronic component that allows current to flow in only one direction. It is used to convert alternating current to direct current through a process called rectification. Diodes come in various types including laser diodes, light emitting diodes, Zener diodes, and silicon diodes. Rectification uses diodes to convert AC to DC through either half-wave or full-wave rectification circuits. Zener diodes are used in the reverse bias mode as voltage regulators. Photodiodes generate current or voltage when illuminated by light and are used in applications like machine vision, range finding, and medical diagnostics.

Ic 555
1.Introduction
The 555 IC was designed in 1971 by Hans Camenzind under contract to SigNetics Corporation.
555 timer is a highly stable circuit used to generate time delays, or Oscillations.
A single 555 timer can provide time delay ranging from microseconds to hours.
It operates from a wide range of power supplies ranging from + 5 Volts to + 18 Volts supply voltage.
2.Pin Configuration
3.Working of Pin
4.555 Integral circuit
5.Operating modes of IC
6. Bistable Mode
In bistable (also called Schmitt trigger) mode, the 555 timer acts as a basic flip-flop.
The trigger and reset inputs (pins 2 and 4 respectively on a 555) are held high via pull-up resistors while the threshold input (pin 6) is simply floating.
Thus configured, pulling the trigger momentarily to ground acts as a 'set' and transitions the output pin (pin 3) to Vcc (high state).
Pulling the reset input to ground acts as a 'reset' and transitions the output pin to ground (low state). No timing capacitors
Pin 5 (control voltage) is connected to ground via a small-value capacitor (usually 0.01 to 0.1 μF). Pin 7 (discharge) is left floating
7.Monostable Mode
Pulse generator circuit which the period is calculated from RC network and connected to external of 555 timer
Stable when the output logic LOW (logic = 0)
When a pulse is trigger at pin 2 (normally negative trigger pulse), timer output will change to HIGH (+Vs) for a while and change to LOW (stable condition). The condition will continue LOW until pulse is trigger again.
The timing period is triggered (started) when trigger input (555 pin 2) is less than 1/3 Vs, this makes the output high (+Vs) and the capacitor C1 starts to charge through resistor R1. Once the time period has started further trigger pulses are ignored.
The threshold input (555 pin 6) monitors the voltage across C1 and when this reaches 2/3 Vs the time period over and the output becomes LOW,
At the same time discharge (555 pin 7) is connected to 0V, discharging the capacitor ready for the next trigger.
8.Astable Mode
Astable multivibrators are also known as Free-running Multivibrator.
Astable do not need trigger pulse for external to change the output.
The period for LOW and HIGH can be calculated based on resistor and capacitor value that connected at outside of timer.
9.Applications
Schmitt trigger
PPM
PWM
Linear Ramp generator
Precision Timing
Pulse Generation
Time Delay Generation
Sequential Timing
Used as a quad timer
10. Conclusion
Hence 555 IC timer can produce very accurate and stable time delays, from microseconds to hours. It can be used with supply voltage varying from 5 to 18 V. Timer can be used in monostable mode of operation or astable mode of operation. Its various applications include waveform generator, missing pulse detector, frequency divider, pulse width modulator, burglar alarm, FSK generator, ramp generator, pulse position modulator etc.

Simulation of a Two Stage High Power Factor Driver for White Power Led
In this paper, an integrated double buck–boost (IDBB) converter is proposed as a high-power-factor offline power supply for power-LED lamps. The IDBB converter features just one controlled switch and two inductors and is able to supply a solid-state lamp from the mains, providing high power factor and good efficiency. In this paper, the IDBB converter is analyzed, and a design methodology is proposed. It is demonstrated that, with a careful design of the converter, the filter capacitances can be made small enough so that film capacitors may be used. In this way, the converter mean time between failures can be made as high as that of the solid-state lamp. A design example for a 70-W converter supplied from a 230 V/50 Hz mains for street lighting applications is shown. MATLAB is applied to execute the whole circuit simulations. Finally, simulation results demonstrate that the power factor of the closed-loop IDBB converter is 0.993 and the output voltage of the designed controller can be stably maintained at 200V.

Benefits of led light in human life
LED lights are an energy efficient lighting technology that uses semiconductors to convert electricity into light. They use 85% less energy than halogen or incandescent bulbs and have a much longer lifespan. While CFL bulbs are also energy efficient, LED lights are better suited for decorative lighting due to their flexibility in design and ability to change colors. LED lights provide many benefits such as long life, energy efficiency, being eco-friendly, and ability to withstand rough conditions. However, most LED lights emit a blue light that uses phosphors to create white light, decreasing efficiency and limiting light in the green and red spectra, though this is sufficient for many applications. LED lights are generally more beneficial than CFLs due

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
